      abstract     = {The differences in the thermophysical properties between
                      tungsten and steel create thermal stress peaks at its
                      interface when joined directly for the breeding blanket of a
                      fusion reactor. In order to solve this problem, a graded
                      interlayer made of several layers of W/steel-composites is
                      considered to reduce these stress peaks. Plasma spraying
                      under an argon shrouded chamber was employed as a cost
                      efficient manufacturing technique for such composites and
                      field assisted sintering technology/spark plasma sintering
                      was used to diffusion bond them with bulk-W and bulk-steel.
                      Firstly, thermophysical characterizations were performed on
                      these composites. Secondly, two approaches have been
                      investigated to join bulk-W and 75 $vol\%$ W composite:
                      direct joining and using a vanadium foil. Only vanadium foil
                      resulted in successful bond formation at all the three
                      bonding temperatures of 800 °C, 900 °C and 1000 °C.
                      Thirdly, investigation of diffusion bonding parameters
                      (temperature and time) for the joining of 25 $vol\%$ W, 50
                      $vol\%$ W, 75 $vol\%$ W and bulk-steel were studied and
                      optimum process parameter were identified. Finally, this
                      optimized parameter (1000 °C; 30 min) was employed to
                      manufacture a complete 12 mm x 12 mm W-steel joint
                      consisting of this graded interlayer.},
